WIN DOW-SHADE FASTENER.

To all whom t may concern:

Be it known that I, GEORGE H. BAKER, a citizen of the United States,residing at Seattle, in the county of King and State of Vashington, haveinvented a new and useful Window-Shade Fastener, of which the followingis a specification.

he present invention relates to window shade fasteners, the object beingto provide a window shade fastener which will permit the shade beinglowered from the to and which will retain the shade in any adjustedposition on the window frame.

A second object of the invention is to provide a shade fastener whichmay be used upon any window frame construction without reconstructingthe saine and which will possess a neat appearance.

A further object is to provide a shade fastener which is easily operatedand which will overcome the disadvantage of the curtain tearing from itsfastenings as is often experienced with shades of the roller type.

An additional object of the invention is to rovide a shade fastenerwhich is simple and) durable in use, consists of' few parts that may bereadily assembled and disassembled and which may be manufactured andsold at a minimum cost.

lVith the above and other objects and advantages in mind, the inventionconsists of combinations of elements, arrangement of parts,constructions and general assemblage which will be hereinafter enlargedupon and claims.

In the drawing: Figure 1 is a front elevation of the device in operativeposition on a window frame; Fig. 2 is an end elevation of the same; Fig.3 1s an enlarged view of one of the locking devices and parts associatedtherewith partly in Section5 and Fig. a is a perspective of one of thelocking plates.

eferring to the drawing wherein like characters of reference indicatelike parts the numeral 5 denotes a window frame of any usualconstruction to which are secured the vertical guide rods 6 uponopposite sides thereof. These rods are formed with eyes 7 at their upperends which are secured to the window frame by fastenings 8. These rodsare spaced from the window frame by bending the upper ends atright-angles as indicated at 9, the rods being extended through eyes 10mounted on the window frame adaJacent the lower ends of the rods.

Specification of Letters Patent. Application led April 15, 1919. SerialNo. 290,269.

Patented Sept. 9, 1919.

A vertically movable bar l1 is provided to which is attached the shade12 and has notches 13 formed in its upper edge at its opposite ends andfurther provided with openings 14 in these ends which receive the guidebars 6.

Locking plates 15 are slidably mounted upon the guide rods 6 and areprovided with longitudinal slots 16 at their inner ends in which pins 17carried by the sash are engaged. These pins 17 are bent at rightanglesto retain the plates in their relative position.

Expansible coil springs 18 are seated in the notches 13 and encircle theguide rods 6 and bear against the under face of the plates l5 tonormally retain the same at an angle to the sash bar so that the plateswill bind on the guide rods and thus retain the bar againstdisplacement.

Flexible elements 19 are attached to the outer ends of the lockingqplates by means of which the plates are moved to a horizontal positionso that the same will be free to slide on the guide rods 6. It will bemanifest that the eyes 10 not only serve to retain the guide rods 6 inposition but serve as stops totlimit the downward movement of theslidable bar.

The embodiment of the invention herein set forth and illustrated isconsidered the preferred construction but it will be understood that theconstruction may be modified in many respects and that my limits ofmodification are only governed by the subjoined claims.

What is claimed is :n

1. A shade fastening comprising verti cally disposed guide rods arrangedupon opposite sides of the window, a shade attaching bar slidablyengaged with the guide rods, an oppositely inclined locking platedisposed at each end of the bar and having pivotal and slidableconnection therewith, an expansible coil spring en circling each of theguide rods and resting upon the bar and urging the locking plates to aposition where the same will bind against the guide rods, and means formov ing the locking plates to a horizontal position against the tensionof the coil springs and to lower the shade bar.

2. A window shade fastening comprising guide rods disposed upon oppositesides of the window, a shade carrying bar slidably engaged with therods, locking plates slid able on the rods and provided with longipermitthe plates to move vertically and tudinal slots at their inner ends,pins carhorizontally, springs bearing against the ried by theshade-carrying bar and disouter ends of the plates and the shadecarryposed in the slots to permit the plates to ing bar, and ieXibleelements depending move vertically and expansible springs from theplates for moving the same against 40 bearing against the outer ends ofthe shade the tension of the springs.
